The Sip-N-Dip Tiki Lounge has been part of the O'Haire Motor Inn since 1962. The main attraction is the mermaid show -- there are windows in the bar that look into the hotel's pool, and mermaids put on a show on weekends. Another attraction is "Piano Pat" Sponheim, who has been playing piano five nights a week — Tuesday through Saturday -- since 1962.

When actress Daryl Hannah, who famously played a mermaid in the movie Splash, was filming in the area, she made a special visit to the bar, even donning a mermaid suit and jumping in the pool to give a show.

In 2003, the bar was featured on a list of the top 10 bars in the world in GQ Magazine. In 2004, a crack in one of the glass pool walls threatened the bar; the glass walls have been replaced with new triple-pane glass.

The bar's ceiling is lined with bamboo, and there are beachcomber-inspired fish trap lamps.

The bar does especially well on weekends during the mermaid show, when patrons line up to get into the small 72-person capacity bar.
